PATENT or -rice CYRIL FREDERICK Jor Ns'ro OF" CROYDON, ENGLAND cARILitoN MECHANISM Application filed November 7, 1927, Serial 'No. 231,756, and in Great Britain December 23, 1926.

This invention relatesto carillon mechanism and has for'its object to provide efficient mechanism of this type particularly applicable to apparatus of the kind having pneumatic or fluid operating-devices'or actions. The present invention consists broadly of carillon mechanism wherein 'm'eans are provided whereby the striking blow of a bell or a number of bells whether effected manually or by fluid motor mechanism controlled from a manual can be supplemented by power when required.

In the preferred form-of the mechanism the bells are struck by fluid motorimech'arii'sm of which the valves are controlled'by electric power mechanism of which the circuits are closed by switches" operated byt hel levers or keys of the foot operated notes or the manual,

or either when the' levers or claviers of the foot key board are coupled with those of the manual.

Each'unit of the power me'chanism'may be provided with two or more motors 'of the a same or different power, and means whereby any of them or any group of them can be brought into operation when desired.

When the bell striking mechanism is'operated by, or supplemented by, fluid operated 3 motors, they may be provided with fluidadmission controlling valves operated'by electric power devices controlled by switches arranged on or near a manual;

Some or all of the bells may be provided with two-or more clappers each operated by a separate motor, the motors being adapted to be brought into operation'singly, or two or more of them simultaneously, from the manual or key board mechanism.

The controlling mechanism for each degree of loudness maybe connected to' a separate manual so that one manual may be used for normal loudness say 7', a second for if and a third for fff, and when fluid operated mechanism is used for the striking mechanism' this may be arranged'to control the bells singly or in groups.

Eachbell striklngmotor may be of the same size and connected to a se arate supply of motive fluid, each supply 0 motive fluid beingat a different pressure from the others, or each bell striking motor may have -'tw'oor' more admission valves leading to a'co minon fluid supply under pressure, the controlling mechanism being arranged to bring into op eration one of them, or any numberof them simultaneously. Also the mechanism transmitting motion from the motors to theclap pers may be provided with any suitable kind of'relay-apparatus. I

- Various manners of carrying 'out the invention are illustrated diagrammatically by the accompanyingdrawings wherein Figure 1 is a general view of -one form of the apparatus, Figure 1 a front view of the manual, Figure 2 a modification of the fluid driven element and Figure -3a modification of the apparatus as applied to a bell having two clappers." p v In these drawings 2 is one of the bells, and 3, 4 and 5-the cylinder of fluid motors say pneumatic motors of which the piston rods 3?, 4c" and-5 operate through arms 3", 4" and 5 fixed on a rocking shaft 6 and operating through the end of the arm 4", the rod 7,

arms 8 and 9 fixed on a rocking shaft 9, link 10, the rod 11 of the clapper 12. The rocking shaft 9 of this clapper operating mechanism can also be operated from a clavier 13 of the manual 13 through a rod 14: and arm 15 fixed on the rocking shaft 9.

The fluid motors in the present example are pneumatic motors having admission valves 3, 4 and 5 connected by passages 3, 4 and 5 to a main 16 leading to a source of air under pressure. The valves 3", 4 and 5 are lifted by electromagnets of which the coils 3", 4 and 5 are connected to a battery or other source of electricity indicated by 17; The circuits of these coils are closed by switches 13" on the claviers 13, a similar set of switches .18" is shown on foot pedals 18.

A controlling switch 19 is provided so that the bells can be rung by the manual claviers 13 or the foot pedals 18. \Vith larger bells such mechanism is insnflicient to strike the bells with the desired force hence the manual force may be supplemented by power upon closing the switch 19 thereby enabling the closing. of the switch 13 and 18 bythe manuals and foot pedals which brings into operation the pneumatic bower devices for each bell.

In the example illustrated the cylinders 3, 4 and 5 are of different powers so that each will operate the mechanism to strike the bell 2 with the clapper 1:2 with .a .blow of difl'erent strength from the others and thereby obtain a different degree of loudness from the bell. Switch stops 3% 4 and 5 are provided for bringing into operation the corresponding cylinders. Thus when the switch stop 3 is pushed in, circuit from the battery 17 can be closed by the olnvier switch 13 through the lead 3" contacts 3 and 3" lead 3", coil 3* and return lead 20, thereby energizing the eleetromagnet lifliing the valve 3 and .zdmitting air under pressure to the cylinder 3 so as to impel tlwough the :aurm rod and link mechanism the clapper 12 against the hell .2. If a heavierstnolce is required the switch stop 4 is pushed in,:so that circuit from the battery 17 can be closed by the clavier switch '13- 'tlnrongrh the lead 3 contacts l and 4 lead 4, coil 4 and return lead 20. thereby energizing the electromagnet lifting the valve 4 and admitting air under pressure to the larger cylinder domes-to impel through the arm, rod and link mechanism the clapper 1-2 against the bellg. Vhen a. still heavier stroke is required the switch stop 5 is pushed in, so that circuit from the battery 17 can be elosed by the clav-ier switch 13" through the lead 3', 5" contacts 5 and 5",, lead 5", coil 5 and return lead 20, thereby energizing the electromagnet lifting the valve 5 and admitting .air under pressure to the largest cylinder 5 so as to impel through the arm, rod and link mechanism theclappcr 12 with still greater force against the bell The same operations can be effected by each foot pedal 11) by means of the switch 1-8" and leads 18* and 18. The pistons of the cylinders 3 are arranged to open an exhaust port when at the lower end of their strokes and suitable springs. weights or other suitable mechanism may be provided for returning the mechanism to its normal position. Also any suitable automatic or non-automatic means may be provided for returning the stop switches 3 4 and 5 to their norn' al positious.

The clavicrs l3 and foot pedals l6 and rod and arm mechanism 14. ll, 14", Hi and 15 may be substituted by a. three manual latboard. one key board being arranged to control directly :1 series of switches corresponding to switches 3*, another a series of switches corresponding to '1' and a. third a series corresponding to 5. the pneumatic mechanism being similar to that illustrated by Figure 1.

In a modification of the apparatus illustrated by Figure l, the three air supply pipes 13. 4 and 5 instead of bci fed by a common supply 16 may each have its own supply of fluid under a different pressure. and in Hrli a case the cylinders- 3. l and 3 may lw of the. same size.

In a modification of the pneumatic |ll it)l.\ as illustrated b Figure 2 instead of three r: \'linder units one large cylindri- 3H l l with three valves 3, 4 and I), each operated by mechanism similar to b unt in Figure l. the corresponding parts being given the sumo reference numerals. 'lhe (bl'jt 'l ol' li!l.\ lumiific'ation is to provide a greater \ulltfltt of air to the cylinder for increasing tln- \t-lnrit ot' the piston according to \\'hi(h stop switch is pushed in and consequently increasethe striking blow on the hell '1.

In the modification illustra-lml by Figure 3,eacl1 hell 2 is provided with two clappers l2 and 40 each being nonnected nespecti-Vcly by links 12%, 40 arms l2", l0 and l2", 40" tixcd on rocking shafts l2. l0 and connected by rods 1, 4O with levers l2. l0". pivoted at 12 and 4 0 and marrying the rods 1:2. ll) of pistons 12*, 470 operating in cylinders 12, 40", the cylinder LZ'" being larger than the cylinder 40" so as to give. a heavier striking blow on the hell .2. The air supply to the cylinders is frame pipe 16 connected by pipes 12 and 40 to the respective cylinders and provided with valves 112 and 144.)". these valves being oontnofled in :a similar manner to those described with reference to l ig-ure l.

The valves 3, 4 and 5 of the pneumatic motors instead of admitting fluid directly to the cylinders 3, 4 and 5 ma y be arranged to operate the pistons of relay mechanism opmating the admission valves proper of the cylinders.

The-electric lead system shown may be sub stituted by any other suitable system. also the. switch stops may be arranged to close circuit when pulled out instead of when pushed in.
